BEATING OR WASHING ENGINE.

SPECIFICATION forming part of Letters Patent No. 606,174, dated June 21,1898. I

Application filed June 10, 1897. Serial No. 640,119. (No model.)

To alt whom it may concern:

Be it known that I, ALLEN A. \VHEAT, a citizen of the United States,residing at West Springfield, in the county of Hampdenand State ofMassachusetts, have invented a new and useful Improvement in Beating orWVashing Engines, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature.

The invention relates to the arrangement and combination, in a beatingor washing engine, of a revolving roll with a screen adapted to beturned into and out of operative relation to it, and to aholder forsaidscreen, which is of peculiar shape and which operates not only to holdthe screen, but to close the opening occupied by the screen when thescreen is in an inoperative position, and also to permit the turning ofthe screen from an operative to an inoperative position while themachine is in operation without producing any opening or space throughwhich the pulp may escape during such movement.

My invention is particularly adapted for use in a beating-engine of thattype in which the pulp is carried completely around the beater-roll, butit may also be used in the ordinary beating-engine, in which most of thepulp passes beneath the beater-roll without being carried around.

In the drawings, Figure 1 is a view in vertical section of a portion ofa heating or washing engine, showing a part of a rotary beating-cylinderand a portion of its inclosing casing and the extension or auxiliarycasing which forms the drum-chamber in which the revolving drum whichcarries the screen is mounted, the screen being in operative position.Fig. 2 is a similar View, representing, however, the screen as ininoperative position. Fig. 3 is a view in elevation, representing thescreen and the drum and its inclosing chamber, looking from the dottedline 3 3 of Fig. 1.

A is a part of a revolving roll of a washing and beating engine which isinclosed in the usual casing A. It rotates in the direction of the arrowin Fig. 1 and its bars throw the pulp and water against the partition atits I is fastened at its edges by staples or other fastening means tothe edge or border 2) of the drum B surrounding arectangular opening band the bars 19 separated from each other by recesses b extendvertically across the opening back of the screen and serve to reinforceand hold it against the pressure of the pulp and water thrown against itby the revolving bars.

The drum B4 is mounted upon the shaft C, which has bearings in or uponthe sides (1 d of the drum-chamber D, and the drum is secured to theshaft and is turned thereby, one or both ends of the shaft extendingthrough the sides and receiving handles (1 by which the drum'may beturned from the position represented in Fig. l to the positionrepresented in Fig. 2 and back.

It will be seen that the drum-chamber D is removably secured to the maincasing A by means ofthe fastening-hooks a, so as to allow convenientaccess to the drum B for repairs or cleaning.

A portion 13 of the drum B opposite the screen Z) is preferably madecylindrical in form, as represented, in order that the close joint at dbetween the lower edge of the stationary partition B and the uppersurface of the drum and section B may be maintained while the screen isbeing turned from its operative position (see Fig. 1) to the inoperativeposition represented in Fig. 2, it being understood that the drum isturned in the direction indicated by the arrow in Fig. 1.

It will be understood that the screen and drum may be turned while thebeating-engine is in operation and while the pulp and water are beingthrown against the screen I) or the cylindrical side B of therevolvingdrum B and that it is not desirable to expose any opening at such a timein such partition through which pulp may be forced and wasted. It istrue that there is an opening formed between the lower part of thescreen and the stationary partition 13 during this turning; but thisopening is not long maintained, and the upper part of the drum andsection B is immediately moved into the space between the screen and thebeating cylinder and serves to receive the pulp and water and act as ashield for covering the opening thus temporarily established.

The drumchamber D forms an extension from the casing A, which covers therotary beating-cylinder and forms the chamber cl of a size to receivethe section B when in operative position.

The drum 13* has an outlet 12 in the cylindrical portion 13 throughwhich water forced through the screen escapes when the drum is in theposition represented in Fig. 1, the water then flowing into the lowerpart of the chamber d, from which it escapes through an escape-pipe d.It will be understood that this screen is used while the pulp beingtreated is relatively coarse, but that after it becomes finer the screenis no longer available and is then moved out of position while theengine is in operation, and the screening may be done by the other orcontinuously-revolving drumwasher now in use on beating-machines.

I would say that it is necessary to turn the screen in one directiononly while the machine is in operation-that is, from the positionrepresented in Fig. 1 to that represented in Fig. 2. The screen isrestored or turned back to the position represented in Fig. 1 when theengine is stationary, being provided with unworked or beaten pulp.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. In abeating or washingmachine the combination with a rotary beating-cylinder, of an inclosingcasing for said cylinder, an auxiliary drum-chamber opening into saidfirstnamed chamber, and a rotary drum to close said opening, said drumbeing provided with a screen on one side and a water-outlet.

2. In a beating or washing engine, the combination with a rotarybeating-cylinder, of an inclosing casing for said cylinder, an auxiliarychamber in proximity to said casing, a partition separating theinteriors of the said casingfand chamber and having an openingtherethrough, a rotary drum having a fiattened screened side and acylindrical imperforate portion which are adapted to be alternatelyinterchanged to close the opening in said partition and provided with-awateroutlet.

3. The combination in a beating or washing engine with thebeating-cylinder A, of the drum-chamber (1 having an opening between itand the cylinder-casing, a drum l3 contained within said chamber cl,means for turning said drum E the screen-partition I3 carried by saiddrum BF, and the curved drumsection B having a water-outlet.

4'.- The combination in a heating or washing engine of thebeating-cylinder A, the case D having a chamber 01 an opening betweenthe said chamber and the cylinder-casing, the partial partitions B, Band the rotary drum B having the screen 13 an outlet, the curved section13 the said curved section B maintaining a close joint with the loweredge or bottom of the partition B as the drum is being turned to movethe screen from an operative to an inoperative position and the sectionB to a position to close the openin 5. In a heating or washing engine,the combination with a beating-cylinder, of an inclosing casing for saidcylinder, an auxiliary chamber, a partition having an opening separatingthe interiors of said cylinder-casing and auxiliary chamber, a screen tospan the opening in said partition, a cover to close the opening, andmechanism by means of which the cover is thrown into operative positionwhen the screen is moved out of operative relation to thebeating-cylinder and the screen is brought into operative position whenthe cover is moved away from said opening.

6. In a beating or washing engine, the combination with abeating-cylinder, of an inclosing casing for said cylinder, an auxiliarychamber removably secured in proximity to said cylinder-casing, apartition having an opening separating the interiors of saidcylinder-casing and auxiliary chamber, a screen to span the opening insaid partition pivoted in said auxiliary chamber, a cover, also pivotedin said auxiliary chamber, to close the opening, and mechanism by meansof which the cover is thrown into operative position when the screen ismoved out of operative relation to the beating-cylinder and the screenis brought into operative position when the cover is moved away fromsaid opening.
